SUBMA'RINE GUN.

SPECIFICATION forming part of Letters Patent No. 491,051, dated January, 31, 1893. Application filed May 28, 1892. Serial No. 433,968. (NomodslJ To all whom it may concern.- I

Be it known that I, JOHN P. HOLLAND, residing at 185 Court street, Newark, in the State of New Jersey, have invented certain new and useful Improvements in Submarine Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the mounting, training, and operatingof submarine guns in torpedo boats and similar structures.

The object of the invention is to produce an efiicient means for the attachment of a large torpedo to the bottom of a ship, so that the torpedo may be afterward fired from adistance.

Figure 1 is a' plan diagram, partly broken away, of boat. Fig. 2 is a sectional plan of broadside guns. Fig. 3 is a muzzle-view of guns and port. Fig.4 is asection of torpedo and attaching harpoon. Fig.5 is a cross section of boat showing gun connterpoise.

A indicates the shell of the submarine boat;

B B denote tangentrods which may operate signals on the boat.v

0 indicates a large gun or mortar having its muzzle attached to the side of the boat, and covered by a cover L, which cover may be swung to one side by turning itspintle M..

Pintle M passes through a tight-bearingin the side of the boat, and may be turned open or closed by lever Q, or held fast by look not Q engaging the pintle and bearing. Lever P operating on a swivel head on the piritle, serves to ease'the movement of the pintle and cover. 1

The mortar O has a-movable breech piece D, perforated as at E for the passage of an insulated electric wire F, which ,wire is snrrounded by a water-tight elastic bushing G where it passes through the breech block.---

A small gun H, having its muzzle pivoted in the shell ofthe boat I, is covered by the same cover L, a passage K under the cover serving to connect the muzzles of the two guns. Catches N hold the cover L tightly closed when desirable; The small gun II is connected by a link to the water telescope T, the link being pivoted to gun and telescope. The gun If is counterp'oised by a weight 20 as indicated in Fig. 5. The water telescope may have a spring cover V. The gun H, be ing held by 1ink S in a definite relation to the telescope, will partake of the movement of the telescope. When the telescope shows a proper aim, gun H may be fired. The gun H will be loaded with a projectile in form of a dart or spike 1, having barbed end and bearing studs 2, which permit wire 3 to pass out the muzzle alongside the projectile, said wire being fastened to the projectile 1, and also to a large torpedo, 5. A part of the wire 3 may be coiled around a spindle, 4, of the torpedo, if .a greater length is desired than will readily lie in the space between the gun and mortar.

The torpedo 5 is loaded into mortar 0, and can be expelled by a small powder charge, or

air pressure. The wire 3 connects projectile 1 in the gun with torpedo 5 in the mortar,- through passage K, the connections being made before cover L is opened, and electric wire F is connected to the torpedo through the breech of the mortar,

The submarine boat being run into prox imity with its enemy, and'the range found by telescope, gun H is to be fired, and its projectile driven into the enemy, serving as an anchor. The boat will now back off, ejecting torpedo'5, which will BWlDgdOWIl under the anchor 1. When the submarine boat has re-l treated to a safe distance, the torpedo may be fired by means of wire F.
